Another disadvantage of linked lists is the extra storage needed for references, which often makes them impractical for lists of small data items such as characters or boolean values, because the storage overhead for the links may exceed by a factor of two or more the size of the data. The following code inserts a node after an existing node in a singly linked list.

Reports on their work appeared in IRE Transactions on Information Theory in 1956, and several conference proceedings from 1957 to 1959, including Proceedings of the Western Joint Computer Conference in 1957 and 1958, and Information Processing (Proceedings of the first UNESCO International Conference on Information Processing) in 1959. Parlante, Nick (2001). In particular, if a new node is added at the beginning of a list, the former list remains available as the tail of the new one a simple example of a persistent data structure. Antonakos, James L.; Mansfield, Kenneth C., Jr. The two links may be called 'forward('s') and 'backwards', or 'next' and 'prev'('previous'). This scheme, handy for creating simple caches, ensures that the most recently used items are also the quickest to find again. Nodes in a linked list must be read in order from the beginning as linked lists are inherently sequential access. Delete &minus; delete an element using given key. In languages that support abstract data types or templates, linked list ADTs or templates are available for building linked lists. firstNode .next.
